To all 'wiz-om it may concern:

lcle it known that l, E :Nnsr fflnnonus u citizen oi. the United ldtutes; residing in the city and county of lien Francisco und tul'e o't California, have invented a new and useful improvement in u filurgicul Device for tlpticul Uperutions of which the following is specification.

.lllv invention relates to improvements in surgical devices :lior optical operations wherein u vocuuni cup opentes in conjunction with means for moving said cup uwey from the hood oil? it patientto remove the eye-bell from its socket or to hold suid evebull against rotation or other niiorernent within so i d socket.

The primary object ol. the present invention is to provide improved means for holdthe eye-bull of a patient against movement duringnmjor surgical operations on said eye-hull.

A further object of the invention t0 gnovide improved nieuns for removing the eyeball from its socket and holding; the

some away from said socket with a constant.

tension to prevent undue strain on the eyebul]. muscles and consequent paralysis of said muscles.

.ilh still further object of the invention is to engege the eye-bell of u patient with a, suction instead of it pressure as in the present state ofthe art thereby tending); to retain the vitreous humor within the eyebell instead oftendinguzo expel it when sold eve-bull has been pierced.

i lnother object of the improvement is to provide improved. means for indicating and re 'ulating the degree of intensity with which the eye-bell is engaged in order to prevent disastrous tension or": the eye muscles.

ll accomplish these and other objects by means of. the inn'n'oved devicedisclosed in the drawings forming it part oi. the present speciticotion wherein like churucters of relerence are used. to designate similar parts throughout the said S1)e(:ilicuti0n and drewinns, and in which llig'. l is at front elevation of the hood ol' u patient disclosing; my device, partly in sci'ztfuiu applied thereto:

The hands ll. end 2 are padded with straps 6 and '7 respectively, which straps continue around the hecd oi? the patient and are provided with suiteble luiclrles 8 and 9 respectively by means oi? which the harnesses may he adjusted and properl secured to the head of said patient.

Projecting fronithe junction of the hands 1 21nd. and :tl'l'tlllgtlfl slightly above and between the eyes of a patient when the herness is applied, is a. boss 11 l wing u tubelur projection 12 provided with e longitudinully disposed slot ll.

A th nded rod ill rotetuhl v mounted within the tube and is provided with an exteriorly located nob 17 by rneons of which said rod 16 may be rotated, the purpose o1 which will hereinafter he more fully set iorth.

nut 18 is mounted upon the rod 16 and extends through. the longitudinal. slot 141; of the tube 12 to engage a. sleeve 1.9 slidobly inoul'ited upon the tube .ilkl]. arm 21 is rotstuhly mounted upon the sleeve 1th said urin being split to pro ide. su'llicient tension to :lfricuonuliy encode the sleeve 19 to norinully prevent rotation of: said arm upon suid sleeve 1.) by n'ieuns of which arrangeinent the said arm fill. may be readily moved to and retained in our desired position uhout the unis ol. the tube The arm S51 is provided with n heud 22 upon which, in turn rotetoblvmounted :1 second arm 23 also split and provided with e lhurnli screw Flat hv menus oi which the tensionhr tl'rin foul on; UfOiTDGIll] of: said urin with the heed 111th) o regulated.

Secured to the tree cud oi the second urin' 526 terminating in. u coneoved whose concavity highly isu tuln vucuui'n cup polished or burnished to prevent a perfectly free surface such as may engage the cornea or eye-ball without injury to the surface thereof.

The other end of the tube 26 has a flexible tubular connection 28 to a bifurcated tube 29 of the vacuum receiver t, which receiver consists of a cylindrical body having piston 31 slidably mounted therein and provided with a cup washer 82 and a graduated piston stem 33 projecting beyond one end of the receiver a, that end of said receiver being also provided with an aperture 23-: to provide easy ingress and egress to the atmosphere displaced within said end of the receiver by movement of said piston 81.

The receiver T is also provided with a valved vent 37 by means of which the vacuum therein may be released.

A spring 36 Within the receiver at tends to normally retain the piston 31 at one end of the receiver 4;.

A second flexible connection 38 leads to a piston 39, provided with a valve etl, slidably mounted within a cylinder 12 having a vent 43 provided above said piston A spring i ltends to retain the piston 39 adjacent the vent end of the cylinder 42, the whole providing a suitable vacuum pump.

In operation the harness is adjusted to the head of the patient with the tubular projection projecting slightly above and between the eyes of the patient as disclosed in Fig. l of the drawings.

After a local anesthetic has been applied the concavity of the vacuum cup 27 is moistened and applied to the cornea or other exposed portion of the eye-ball oi the patient, the rod 16 being rotated by the nob 17 to move said cup 27 to its proper position to engage said eye-ball.

13y manipulation of the vacuum pump air in exhausted and a vacuum thus produced within the receiver 4, which vacuum actuates the piston 31 to compress the spring 36 and move the graduated piston stem 33 inwardly thereby readily indicating the degree of intensity of the vacuum within the receiver t. The vacuum within the receiver is transmitted, through the flexible connection 28 to the vacuum cup 27 thereby causing the eye-ball of the patient to adhere to said cup.

It is evident that the degree of adherence of the eye-ball to the cup 27 may be regulated by the amount of vacuum created or produced by the vacuum pump and also by the screw 37 of the receiver at. By opening or unscrewing saidscrew 37 air is admitted to reduce the vacuum within said receiver. The screw 37 may also be used to entirely release the vacuum within the receiver 4t to release the eye-ball -from. the

cup 27 when the operation is completed.

After a. suflicient degree oi. intensity of the vacuum has been obtained the nob 17 is rotated to move the nut 18, sleeve 19, arms 21 and and the vacuum cup QT, thereby removing the eye-ball from its socket the required distance.

As the eye-ball is firmly attached to the cup it is evident that the patient cannot rotate or otherwise move the eye-ball during the operation.

It is also evident that the eye-ball being held by suction there will be no pressure which might tend to remove the vitreous humor when the eve-ball is picrccd.

lily means of this novel arrangement the eyeball may be held away from its socket without danger ct unduly stretching the delicate musc es oi} the eye and thereby causing paral s of said nuisclcs as a dcgree oi vacuum intensity may be produced tor holding the eye-ball which is slightly less than a dangerous tension of said musclcs. under which condition the tension of said muscles will readily detach the eye-ball from the 'acuum cup 27 before the said cup :27 is moved, by meai'zs ot the mcclnmically operated rod 16, to a point or distanr'c where such dangerous tension of said muscles will obtain.

Butter the operation the screw $.37 is operated to release the vacuum within the receiver it and cup o release the eye-ball from said cup. (hthe cup 27 may be moved by means ol. the rod in to return the eye-ball into the socket before the vacuum is released 'l ron'i the cup 27.

It is obvious from the foregoing that l have provided new and improved surgical device for optical operations wherein the eye-ball may be easily removed from its socket without injury and held against movement curing the operation.
